For many years the Maryland State Highway Administration has used a double surface treatment on highway shoulders to provide for shoulder stability and an audible and surface texture warning to motorists who leave the traveled way. With the growth of multi-speed bicycle sales and use, these shoulders were found to be unsuitable for sustained bicycle travel. Asphalt slurry seal was applied to a shoulder section over existing double surface treatment and observed for an 18 month period, to evaluate its adequacy as a low cost bikeway surface. Results of this evaluation indicate that this material is suitable as a shoulder overlay with certain limitations. It provided a smooth surface, adequate for sustained bicycle travel.
